You're easily the worst poster in this thread (and that's saying something) did you even read the post you were replying to? Every word was fact. The only MMOS with 1 million subs in EQ's heyday were Asian games like Lineage.
In any event 500,000 subs is 7.5 million a month (actually a little less assuming 3-month/6-month discounts but whatever, let's call it 7 million). That's 84 million a year which I assure you is a huge success and except for initial starts (e.g. AOW had like 800k at start but that dropped quickly) wasn't really eclipsed by any MMO except WoW until the ftp paradigm became common. And, as we all know, comparing sub numbers to ftp numbers is hard to do because no company I know releases free to pay dollars. I'd be shocked if GW2 with 1 million ftp players was making that kind of money on a yearly basis (possibly except for their first year due to box sales).
